NOAA Global Analysis – November 2013

by Sabrina I. Pacifici on December 17, 2013

“The average temperature across global land and ocean surfaces during November 2013 was record highest for November in the 134-year period of record, at 0.78°C (1.40°F) above the 20th century average. This surpasses the previous record set in 2004 by 0.03°C (0.05°F) and is also the sixth highest monthly departure from average among all months on record and the highest since March 2010, one of the last months in which El Niño conditions were present in the eastern and central equatorial Pacific Ocean. During November, warmer-than-average temperatures across most of the world’s ocean surfaces contributed to the anomalous warmth. Even with ENSO-neutral conditions holding for the 19th straight month, the November global ocean temperature tied with 2009 as the third highest for November, at 0.54°C (0.97°F) above the 20th century average.”

  • “The combined average temperature over global land and ocean surfaces for November 2013 was record highest for the 134-year period of record, at 0.78°C (1.40°F) above the 20th century average of 12.9°C (55.2°F).
  • The global land surface temperature was 1.43°C (2.57°F) above the 20th century average of 5.9°C (42.6°F), the second highest for November on record, behind 2010. For the global oceans, the November average sea surface temperature was 0.54°C (0.97°F) above the 20th century average of 15.8°C (60.4°F), tying with 2009 as the third highest for November.
  • The combined global land and ocean average surface temperature for the September–November period was 0.68°C (1.22°F) above the 20th century average of 14.0°C (57.1°F), the second warmest such period on record, behind only 2005.
  • The September–November worldwide land surface temperature was 1.08°C (1.94°F) above the 20th century average, the third warmest such period on record. The global ocean surface temperature for the same period was 0.52°C (0.94°F) above the 20th century average, tying with 2009 and 2012 as the fourth warmest September–November on record.
  • The combined global land and ocean average surface temperature for the year-to-date (January–November) was 0.62°C (1.12°F) above the 20th century average of 14.0°C (57.2°F), tying with 2002 as the fourth warmest such period on record.”
